You can now have the Check_MK Discovery check automatically repair things by adding missing services or even removing vanished services. This is activated by using the new rule set Periodic Discovery Check instead of the previous (now deprecated) global option Enable regular service discovery checks. In the new rule set you can activate and configure this feature on a per-host base.
Also the discovery check can now warn about vanished services. The default is that vanished services will not set the state to WARN, however, and just display them. So unless you change the configuration the behaviour of the discovery check has not changed.
Note: Automatically removing vanished services can be dangerous as broken things like missing file systems or even switch ports that went down will be removed from the monitoring! Only use in special situations where this is no problem.
